ColorPicker

The color picker (ColorPicker) is used to browse through and select colors. By default, it lets people navigate through colors on a color spectrum, or specify a color in either Red-Green-Blue (RGB), or alpha color code; or Hexadecimal textboxes.

Usage

Basic
Alpha & Preview
Use alpha slider and preview option in the BitColorPicker, allowing to adjust the transparency of the color and preview the result.


Binding
The color type (hex or rgb) of the BitColorPicker automatically matches the initial value of the Color parameter. For example, if the initial value of this parameter is in hex format, the component will return the resulting colors in hex and vice versa.


RGB:

Color: rgb(255,255,255)



HEX:

Color: #FFFFFF



Two-way binding:

Events
